origin

It is possible that as a simple geometric shape, like for example the triangle, circle, or square, the hexagram has been created by various different peoples with no connection to one another.

The hexagram is a mandala symbol called satkona yantra or sadkona yantra found on ancient South Indian Hindu temples built thousands of years ago. It symbolizes the nara-narayana, or perfect meditative state of balance achieved between Man and God, and if maintained, results in "moksha," or "nirvana" (release from the bounds of the earthly world and its material trappings).

Another theory, though apparently not very substantiated, about the origin of the shape is that it is simply 2 of the 3 letters in the name David: in its Hebrew spelling, David is transliterated as 'D-V-D'. In Biblical Hebrew, the letter 'D' (Dalet) was written in a form like an upside-down and backwards "L", but when seen in the Greek, the letter "Delta" (Δ) is a triangle. The symbol may have been a simple family crest formed by flipping and juxtaposing the two most prominent letters in the name. The letter "W" in this case could reference the compositing operation of the two Deltas.

Some researchers have theorized that the hexagram represents the astrological chart at the time of David's birth or anointment as king. The hexagram is also known as the "King's Star" in astrological circles.

In antique papyri, pentagrams, together with stars and other signs, are frequently found on amulets bearing the Jewish names of God, and used to guard against fever and other diseases. Curiously the hexagram is not found among these signs. In the great magic papyrus(Wessely, l.c. pp. 31, 112) at Paris and London there are twenty-two signs side by side, and a circle with twelve signs, but neither a pentagram nor a hexagram.
